To all whom, it may concern/.-

Be it known that I, Fnnnnnron Mums- HEIMER, of Kansas City, county ofJackson, and State of Missouri, have invented a new and usefulImprovement in Car-Movers, of which the following is a specification.

This invention relates to car-movers of the type embodying a bar orlever adapted to fulcrum or pivot on a fulcrum-block resting on thetread of the rail and connected with the bar, so that as the bar isadvanced in following up the car-wheel the fulcrum-block will be carriedalong with it to take a new grip on the rail.

The invention consists, mainly, of an improved connection between thelever and the block which while permitting a pivotal motion of the leverwith reference to the block in order to engage the car-wheel and forcethe car forward will when the bar is advanced along the rail to followup the ear hold the block closely up against the bar and cause it tomaintain its operative relation to the bar ready for a new action of thelatter, thereby avoiding the necessity of using the hand or foot to setthe block in. proper position.

The invention consists also in the details of construction andcombination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of myimproved device, a portion of the car-wheel, and a portion of the rail,the said device being shown in operative relation readyfor action. onthe car-wheel. Fig. 2 is a front elevation of the same. Fig. 3 is atransverse sectional elevation on the line a a of Fig. 1.

Referring to the drawings, my improved device comprises as its essentialfeatures a fulcrum block or frame A, adapted to rest on the tread of therail, a bar or lever B, sustained by the block and adapted at its lowerend to engage the tread of the car-wheel, and a connection 0 between thelever and the block adapted to hold the parts together and permit thelever to be moved relatively to the block in its action on thecar-wheel.

The fulcrum-block S is in the form of an arched plate, comprising afront upright limb a, a rear upright limb a, and a forwardly anddownwardly sloping connecting portion a, the lower ends of the limbsbeing formed with notches a provided with knife-edges a, adapted to spanthe sides of the tread of the rail, as shown in Fig. 2, and thusmaintain for the time being a firm grip thereon. At

its upper elevated end. the connecting portion a of the fulcrum-blockhas rising from it a fulcrum-pin D, on which the lever B is seated so asto rock or fulcrum, the said lever being formed on its under side with acounterbore or conical socket b to receive the pin and prevent arelative slip of the parts, as the lever is moved up and down in itsaction against the car-wheel.

The connection C between the lever and block constitutes the mainfeature of my in vention and consists of a U-shaped link hav ing itshorizontal portion 0 extending loosely through. a horizontal hole in thelever and having its two legs 0'' and 0 extending downwardly throughopenings a and a in the sloping connected portion a of thefulcrum-block, which legs are encircled by spiral springs E E, hearingat their upper ends against the under side of the block and bearing attheir opposite ends against pins 0 extending through the legs at theirlower ends, the tendency of the springs when thus arranged being to holdyieldingly and. close up against the lever, with the fulcrum-pin engagedin the socket of the lever.

in the operation of the device the fulcru1nlock is set squarely on thetread of the rail, with the lower end of the lever engaging at its uppersurface against the tread of the carwheel. The upper end of the leverbeing depressed, it will fulcrum on pin D, causing its lower end to riseand forcing the wheel forward, the spiral springs being compressed andplaced under a tension as the legs of the link are drawn outward throughthe fulcrumblock. In advancing the device to take a new grip infollowing up the car-wheel the upper end of the lever is elevated untilits ower end rests on the tread of the rail, and it is then slid forwardon the rail until its lower end is again in position to engage thecarwheel, the spiral springs in the meantime expanding and acting toforce the fulcrum-block up against the lever and maintain it there, sothat when the block is lowered onto the rail it will occupy its properoperative relation to the lever, and the latter will be ready for actionwithout further adjustment or set of the look. It is seen, therefore,that the springs will at all times when the pressure 011 the le ver isrelieved maintain the block closely up against the lever in its properposition for action of the lever on the car-wheel, thereby avoiding thenecessity for using the foot or hand to position the block. The holes inthe IIO block, through which the legs of the connecting-links extend,are elongated in the longitudinal direction of the block in order topermit the link to tip slightly in the pivotal action of the lever, soas from binding.

The essence of the invention resides in the connection between the leverand fulcrumblock, which connection while permitting of a pivotal motionof the lever with reference to the block will maintain the latter closeup against the lever, and thus insure its proper operative relation tothe lever when the latter is moved up in following the car-wheel.

. l Having thus described my invention, what I claim is-- 1. In acar-mover, the combination with a fulcrum member adapted to rest on therail, of a cooperating lever adapted to engage the car-wheel andsupported by and having apivotal motion with reference to the fulcrummember, and a spring acting respectively on the lever and fulcrum memberand tending to draw them together.

2. In a car-mover the combination of a fulcrum-block adapted to rest onthe rail, a lever pivoted to said block and adapted to be engaged withthe car-wheel, and means forholding the block yieldingly against thelever.

3. In a car-mover, the combination of a fulcrum-block a lever, a linkconnecting said parts pivotall and a spring acting respectively againstthe block and link.

4. In a car-mover, the combination of a fulcrum-block, a lever adaptedto fulcrum to prevent the parts 6. In a car-mover, the combination of afulcrum-block, a fulcrum-pin extending upwardly therefrom, a leverprovided in its under side with a socket to receive the pin and movablerelatively to the same on an axis coincident with the end of the pin,and a link connection between the lever and block.

7. In a carmover, the combination of a fulcrum-block adapted to rest onthe rail, a cooperating fulcrum-lever, one of said parts having a socketand the other a fulcrum-pin to enter the socket, the said lever beingmovable relatively to the block on an axis coincident with the end ofthe pin, and a connec- 1 tion between the lever and the block.

In testimony whereof I hereunto set my hand, this second (2d) day ofJanuary, 1906,

in the presence of two attesting witnesses. FREDERICK MERISHEIMER.WVitnesses JAMEs B. Pnox, FRED B. MERTsHErMER.
